7.2.2.4: : Represent real-world or mathematical situations using equations and inequalities involving variables and positive and negative rational numbers.

7.2.3: : Apply understanding of order of operations and algebraic properties to generate equivalent numerical and algebraic expressions containing positive and negative rational numbers and grouping symbols; evaluate such expressions.

7.2.3.1: : Generate equivalent numerical and algebraic expressions containing rational numbers and whole number exponents. Properties of algebra include associative, commutative and distributive laws.

7.2.3.3: : Apply understanding of order of operations and grouping symbols when using calculators and other technologies.

7.3.2.3: : Use proportions and ratios to solve problems involving scale drawings and conversions of measurement units.

7.3.2.4: : Graph and describe translations and reflections of figures on a coordinate grid and determine the coordinates of the vertices of the figure after the transformation.

7.4: : Data Analysis & Probability

7.4.1: : Use mean, median and range to draw conclusions about data and make predictions.

7.4.1.1: : Determine mean, median and range for quantitative data and from data represented in a display. Use these quantities to draw conclusions about the data, compare different data sets, and make predictions.

7.4.1.2: : Describe the impact that inserting or deleting a data point has on the mean and the median of a data set. Know how to create data displays using a spreadsheet to examine this impact.
